Instructions
Sit down on a bench that has been set to a 30-45 degree angle, with a dumbbell in each hand, resting on top of your thighs. Bring weights up to shoulder height, then lie back on the incline bench. Keeping a natural curve in your back, tuck your shoulder blades back and down and push your feet in to the floor. Position dumbbells directly above your upper chest with your arms extended and your palms facing away from you. Lower the dumbbells in an arc shape down to the side of your chest. From here, press the dumbbells back up in the same arc pattern to the starting position. Repeat for the desired number of repetitions.
Tips
The higher the incline, the more this exercise will work your upper chest and shoulders. To maintain a strong upper back position, focus on pushing your chest out through the whole movement.
